PAYMENT- We accept money orders, personal checks, Google Checkout, & Paypal.

CONDITION- Our scanner makes colors a little lighter. We have lightly tinted windows, which may alter the colors slightly when we use a camera. Vintage items will show some age, and we will try to note any and all defects. An item described, as "excellent", can be perfect or have minor flaws, from age, and that I feel any collector would be glad to have. If you have any question on condition, please ask.
